how it works
talk first. make second. no surprises.
Bring a sketch, a broken part, a napkin drawing or a finished CAD file. Four stages, one point of contact, and you keep the files at the end.

discovery
Bring sketches, references, a broken part, a CAD file — anything.

We digitize, model or scan. You see renders and a quote before anything is made.
